In the last few decades, the world economy has witnessed the expansion of trade, especially in the number of exchanged varieties, the so-called “extensive margins”. In a theoretical model where extensive margins in both tradable and non-tradable sectors are endogenously determined, it is...

We combine the real business cycle small open economy framework with the endogenous growth literature to study the productivity cost of a sudden stop. In this economy, productivity growth is determined by successful implementation of business ideas, yet the quality of ideas is heterogeneous and...

Using a heterogeneous firm model with firm entry and endogenous markups, I study how the financial constraints of exporting firms affect exchange rate pass-through behaviors. I find that the financial constraints increase the degree of exchange rate pass-through.

In the last few decades, the world economy has witnessed the expansion of trade especially in the number of exchanged varieties, the so-called "extensive margins". In a theoretical model where extensive margins in both traded and non-traded sectors are endogenously determined, it is shown that...

This paper analyzes equity and bond positions in a two-country DSGE model where the number of varieties, i.e. extensive margin is endogenously determined. Households take care about not only the price of goods but also the variety of goods they consume. The welfare-based real exchange rate...

This paper investigates a consumption-real exchange rate anomaly from the open macroeconomics literature known as the Backus-Smith puzzle. We both analytically and quantitatively examine how an expansion of trade along extensive margins can contribute to the puzzle's resolution. Our argument is...

I present a dynamic fixed cost model of export participation extended by a capital theoretic concept of the customer stock. Plants that want to start exporting have to invest into a market specific factor which serves as input into a decreasing returns to scale technology generating sales...

This paper studies the effects of foreign exchange (FX) interventions in a two-region New Keynesian model where governments issue both short-term and long-term bonds. Imperfect substitutability between bonds gives rise to portfolio balance effects that make FX interventions effective....

Exchange rate movements affect the economy through changes in net exports, i.e. the trade channel, and through valuation changes in assets and liabilities denominated in foreign currencies, i.e. the financial channel. In this paper, I investigate the macroeconomic and financial effects of U.S....

We examine the causal relationship between US monetary policy shocks, exchange rates and currency excess returns for a sample of eight advanced countries over the period 1980M1 to 2022M11. We find that the dynamics of the US dollar exchange rate is the main driver of currency excess returns. The...
